As shown inFig. 1 1. the bottom of the carburetor 10 is` prodraining thebowl of thecarburetor. The l improved ,form of heating' device assoeiated with thecarburetor' l0 is, more clearly shownin Figs, 2te 5-'nnd includes acasin 1 4' having y .witha luternl opening 16 arranged; adjacent theclosed end,7thel,casing 14 having-nn annular Bange-.17 arranged djucentt e opening-1Q .whilefthe portion ofthe-casing opposite the liane 17i isscrew-threaded as :it 1 8 .for threade engagement with an openingprovided in the lower end of the carbureter 10. When so positioned, thethreaded end of the casing 11i rojects'outwnrdly of the carbureter 1031slown in Fig. 2 und is adapted for the reception of n lock nut l.7"whereby the same may be locked in position, it being Patented June 19,1917.

onej'end closed. hsat 15 les washers 17" may be positioned between thefiange 17, nut 17* and the wall of the carT bureter. The threaded end ofthe casing 14 vided therein register with similar grooves 22 provided inthe outer end of the casing 14, and within which registering ooves arepositioned retaining elements, as' e s 23. A metallic terminal plugY 24is forci ly positioged within the bore of the insulator bushingI 19, andas shown in Fig. 2, the terminal plug and insulator bushing are'provided with coperating shoulders which will limit the inward movementof the plug.- 'As shown, the plug is of such length as to permit theinner end thereof projecting beyond the inner-.fend of the bushingforpurposes of attaching the resistance wire thereto.'

Thel inner projecting end of theplug 24 is provided with a terminalopening 25 comi.

municating with the transverse bore 26' and the resistance 'wire 27 hasone end thereof introduced into the terminal bore 25 and laterallydirected into the?, ransverse bore 26 and retained in such posi ionV bythe fastening pin 28. The resistance .wlre 27 is arranged withina'metaltubing. 29 which has one-end extended into the. opening 16provided in the casing 14 while the other end of the tubing 29'is-closed as by4 a metallic plug 30. The outer end of the resistance wire27 is passed through an opening) provided in the plug` 30 and-is adaptedto eengaged by a wedge pin 31 for retaining the` same in position. Asshown in Fig. 2, the resistance wire 27 supports av luralityof beads 32which may be of any now'n noxiconducting` material as agate, which willhold the resistance-wire spaced from the tubing 29 to reduce frictionand Wear on the wire as well as damage whichv mi ht` be caused by short'circuiting The tubing, 29

as'shown in Fig. 2, has been twisted at right angles from its operative4position for purposes of illustration and it is to be assumed that thetube is in the z position 'shownin Fig. 1 when operatively arranged.

The outer projectin -end of the terminal plug 24 has a thread@ extension33 adapted for the reception of'authumb nut 34 for.

clamping the metallic wire holder 35 thereto, the wire holder 35carrying the wrapped -Wire 36 which extends to the rear of and issuitably connected to the switch plate 37 upon the instrument board 38of an automobile. As shown in Fig. 1, the switch late is provided with ahand switch 39, a lig t bulb 40 and a push button 41. When the switch 39is turned to close a circuit, one-half of the source of electricity isthrown in circuit with the Vresistance wire 27, and simultaneously withthe closing of the circuit, the light bulb 40 is illuminated to'Aindicate that the device is properly circuiting. The current passes fromthe wire 27 to the plug' 30 and tube 29 which'is in intimate contactwith the carbureter 10 for heating the contents thereof, as will beplainly obvious. It is to be understood that in extremely cold weather,the switch 39 may be left turned on -I ent and while the form'of theinvention herein shown and described is what is believed to be thepreferred embodiment thereof, it is neverthele' to' be understood thatvarious forms, modifications and arrangements of the parts may be madewithout departing from the spirlt and scope of the invention as claimed.
